SWMM 4 Temperature File Format

A version of the SWMM 4 ASCII temperature file is read by SWMM 5 if the keyword

#SWMM4_TEMPERATURE

is found in the Titles/Notes Category. The SWMM 5 ASCII temperature file is similar to the file read by the TEMP block in SWMM 4. The main difference is a mandatory first data line consisting of the file format description. The format of the line is a description of the data column followed by the actual column index. If the station number is 0 then the SWMM 5 engine will not read a station identifier (as in this example).

 An example of the format of the SWMM 4 daily temperature file (ASCII) is as follows:

station 0 year 1 month 2 day 3 Tmax 5 Tmin 6 //
1951 1 1 29 36 21
1951 1 2 29 36 21

The SWMM 4 daily file has one minimum and one maximum temperature per day. 

The extraneous average temperature in column 4 is ignored by the program in this example, but the Maximum and Minimum daily temperature is read from columns 5 and 6 respectively.
